| Amp | The basic unit of electric current. Equal to 1 coulomb per second |
| Battery | A group of chemical cells connected together to generate direct current electricity. |
| Chemical Cell | A device made of an electrolyte and two electrodes that makes direct current electricity |
| Circuit | A circle of electricity usually consisting of a power source, a wire, a switch, and an electrical device. |
| Conductor | A material that electricity flows through easily. |
| Coulomb | A unit of electrical charge. Equal to 6.24 billion billion (lots of ) electrons. |
| Current | The flow of electricity. Measured in amperes (amps) |
| Direct Current | An electric current that travels in only one direction |
| Distance | A amount of length, usually measured in meters |
| Electricity | The energy of electrons flowing through a conductor |
| Electric Force | The force that causes electrons to move or flow in a conductor |
| Electron | A negatively charged particle found in atoms |
| Hertz | 1 time (cycle) per second |
| Insulator | A material that electricity does not flow through easily. |
| Joule | a unit of energy or work |
| Kilowatt hour1 | A unit of power. Equal to 1000 watts. |
| Kilowatt hour2 | A unit of electric energy used by power companies. |
| Kinetic Energy | Energy that is actively doing work |

| Magnetic Field | A region of space around a magnet in which magnetic forces are noticeable. |
| Meter | a unit of distance |
| Newton | A unit of force |
| Parallel Circuit | A circuit where electricity passes through more than one pathway at the same time. |
| Potential Difference | The difference in the charge between two points in a circuit. |
| Potential Energy | Stored energy that can do work in the future |
| Power | The rate at which work is done (how fast work gets done). |
| Proton | A positively charged particle found in atoms |
| Resistance | The opposition to the flow of current in a circuit. |
| Series Circuit | A circuit where electricity passes through only one pathway. |
| Static Electricity | Electricity where the charge is not moving. When Charge builds up and moves once. |
| Volts | A unit ofthe pushing force of electricity. Also called the potential difference or electromotive force. |
| Watt | A unit of power. 746 watts equal 1 horsepower |
| Work | The result of using a force to move and object over a distance (Force * Distance) |
| Parallel | A ciruit that allows on bulb to stay lit even if the other bulb is removed. |
| Series | A ciruit where a bulb will NOT stay lit if the other bulb is removed. |
| AC | Alternating Current |
| DC | Direct Current |
| Ohm | A unit of Resistance (to the movement of electrons) |
| Ohm's Law | decribes the connections between current,voltage, and resistance. |
